AMD's private cloud handles all of the semiconductor maker's design projects worldwide. To make it happen, AMD put more than 15,000 servers and storage devices on the same releases of OS, file system, storage management, and cluster software. AMD's cloud runs on more than 115,000 CPU cores and more than 4 PB of storage. The cloud architecture means AMD can quickly reprioritize resources. Last year, it needed to shift massive amounts of compute power to a team working on a new x86 processor core. IT reallocated capacity over night to give the team about 45% of the cloud, letting it do two months of testing in five days.
